Question

Suki buys dog food in 13.4-pound bags. She feeds her dog 0.3 pound of food twice a day. How many full days will the bag of food last?

Answer 1

The food lasts `22.3` or `22` days.

Explanation:

We know she feeds her dog `0.3` pounds `2` times a day so we multiply `0.3` by `2` to know how much she feeds in one whole day

`0.3 xx 2 =0.6`

All we need to do now is divide the big number by the smaller one.

`13.4 -: 0.6 = 22.3`

To check the answer you would then take your answer `22.3` and how much shes feeding him a day `0.6` and multiply them together:

`22.3 xx 0.6 = 13.38` (When we round `13.38` up we get `13.4`)

This answer is `13.4`. Which is how much is in the whole bag, this is how we know our answer (`22` days) is correct!
